Im going through the exact same thing. Met a girl, known her for about 3-4 months and we get along great. We both smoke reefer, we have an interest in antiwar stuff, we even go bed and get up at the same hours. And I do feel depressed because I feel that she is way outta my league. I mean, this girl is a STUNNER, it doesnt matter to me if shes got makeup on or not, I dont care how her hair looks, its always amazing. Shes just the epitome of beauty, but I dont love her for her looks. I love her because she is such a caring person, a giving person, and she just makes me happy to be around. Not like other girls where Ive only been truly happy when in the sack, she can just be playing the guitar and singing and that on its own makes my heart melt.
Dont know if I can offer any advice, Im just rambling on here

Edit: fuck it, im gonna ring her now and see if shes at home. If she is, im gonna ask to come round. I cant hold my feelings in any longer.
